Hi Thomas,
if you don't delete the objects you receive, because you still need
them then it is not a memory leakage problem, but a simple case of
memory usage. To prevent your program from using excessive amounts
of memory you must delete once in a while the objects you've received.
As shown in the hserv.C example, the received histogram is deleted after
it has been drawn.
Cheers, Fons.
